- The 'osd min down {reporters|reports}' config options have been
renamed to 'mon osd min down {reporters|reports}', and the
documentation has been updated to reflect that these options apply
to the monitors (who process failure reports) and not OSDs. If you
have adjusted these settings, please update your ``ceph.conf''
accordingly.
- New pools now have the HASHPSPOOL flag set by default to provide
better distribution over OSDs. Support for this feature was
introduced in v0.59 and Linux kernel version v3.9. If you wish to
access the cluster from an older kernel, set the 'osd pool default
flag hashpspool = false' option in your ceph.conf prior to creating
the cluster or creating new pools. Note that the presense of any
pool in the cluster with the flag enabled will make the OSD require
support from all clients.
